Good for you! Use a drop of glycerol (= glycerin)
and seal the edges of the coverslip with nail varnish.
If you have no glycerol, corn syrup will do. If
the slides have to be kept for years, you'll need to
mix something that sets by itself and contains an
antibacterial preservative. For lipid stains (oil
red O, Sudan black B etc) the pH doesn't matter.
For most other purposes (immunofluorescence, alum-
heamatoxylin, basic dyes) it should be above 7.
